This lab demonstrates a simple method for determining
the stiffness constant of a plastic spoon, is inexpensive, easily
accessible, and quite memorable. The key concepts of Hooke’s
law and linear elasticity are easily explored as well as more advanced structural engineering concepts. One can even
introduce recoverable strain energy (energy stored in the
bent spoon) to discuss concepts of potential energy in elastic
media. Authors’ warning:the discussion of recovering potential energy from a bent spoon inevitably leads to the topic
of projectile motion and soon your class may devolve into a
projectile launching contest.
